Cannot import name ARRAY (sqlalchemy)

Cannot import name ARRAY (sqlalchemy)

Closed this issue 8 years ago · 5 comments

Hi, running hv_grid.py from ego.powerflow exampels I get the following error:

  from sqlalchemy.dialects.postgresql.base import ARRAY
ImportError: cannot import name 'ARRAY'

I can import ARRAY though from sqlalchemy.dialects.postgresql

Using sqlalchemy 1.1.4

Anyone similar problems?

Solving this (just by another import) I know have the error 'ResBus' as well #9 . I merge the dev branch into features/clustering. (inside the ego.powerflow repository) Was that not a good idea, or should I take the master?

@simnh : I posted the 'quick and dirty' workaround in #9 ... but it works for now. Does it work for you?

works with the solution from issue #9

I'm interested in solving this issue without working around it.

I can't find any import like

  from sqlalchemy.dialects.postgresql.base import ARRAY

Neither in ego.io nor ego.powerflow. We changed the all to SQLAlchemy >=1.0.15 compatible statement. Which version of ego.* are you using?

Yeah I was on a old commit in ego.io, where this ARRRAY was inside the code somewhere. Now with being on v.0.0.2 on both repos it works! see (wrote it here as well #9)
